Well built with wonderfull distortion

By papaki72, 11/02/2019
I am using it to boost some distortion to my guitar on the Marshal Mustang II (v2) amplifier. It does it well! Strong and rich with many ways to shape it up to your taste. Limit the overdrive channel of your amp to a quarter and start cranking up the distortion up to where you like it. It can be smooth and just enough to give some taste of distortion to your clean tone, or loud with a hard bite to make your shredding as angry as ever.
I do not use much its overdrive as I am happy with what my amp gives on it.

the pedal graouh

By THE BALD, 29/05/2014
The box to the presentation of the effect is pretty, it is an overdrive / distortion pedal, but this choice is what is what is wrong important.Pas button 1 settings for overdrive or distortion, the second for the gain and volume, bass and treble 3rd and 4th contour. it seems to me there an analog pedal, lots of choices to find the settings or sounds désirés.On has the possibility of a connection connected via a 9 volt adapter (not supplied) or a square cell with access from below remains impractical because unscrew with a screwdriver one cache, me who do not like cables and rather adept batteries, this is not the foot.

UTILIZATION

there is a manual provided (what utility), I'm not an expert but the only thing I trust is my ears.
(The only reliable thing) rendering is necessarily Marshallian, with sustain and saturated fat but perhaps with specific settings and made the amp, all can play rock, blues, metal, for the death and other derivatives must be something else like pedal once the settings found is happiness.

SOUND QUALITY

overdrive with the tube screamer amp gives a warm saturated with lots of harmonics, with sounds very 80's, the only pedal on the amp (5 tsa course), allows to attack more trash registers. I started to play a gibson sg standard (standard config) and a modeling amp sea., line 6 spider 3 15 watt integrated effects of sea .. the sound of the sea.
Then I recently bought a yamaha 5 tsa and there was this little box graouh flourishes above, the amp is not efficient for large saturation, the jh 1 is expressed, I complement a multi purpose zoom g3, which allows me to complete the pre-mentioned effects with delay, chorus and various tests ... There is a large grain in this small pedal with good bass, it's heavy, ideal for métal.Le its my favorite is when it is connected directly to the clear sound of the amp with a boost (g3) in addition.

OVERALL OPINION

If I recommend this pedal? Necessarily ... I tried store on an amp blackstar ht 1, in comparison with other pedals, the blackstar ht distortion, the mxr zw, and it was the cheapest but also the best for me as the prize ... after all it is a matter of gôut.ah yes I almost sell when I played on the line 6, on my tube amp c is made even more so I keep.
the price? I never put more than 100 euros in an overdrive, I do not play in a group so ...
The only advice I can give, try the other one, try the same deal if you can, hoping that it cleans you cages honey.

Marshall pedal in a?

By albou, 03/09/2013
Marshall a good solid type pedal overdrive / distortion and a reassuring weight when she was in labor.
The steel tank probably contains an analog technology, which (it seems) to find the legendary sound of Jim.
It is a type of pedal quite classic with an inlet, an outlet, a 9V supply and the possibility of a battery connection. In short, we found it (and this is not frowned knobs available, see below!).
No bold innovations in all, but ... the dear reliability, reliability!

UTILIZATION

Here we address the issue that is debatable.
The JackHammer has 4 knobs with 3 doubles, for a total of seven settings. Just that!
A button 2 position to choose OD or distortion (this is not progressive as the Boss OS-2, but we will not complain ...), volume, gain, bass, treble, frequency, contour.
I still have a little trouble to find the position that suits me with a simple tone knobs on a pedal, then with four settings for frequency, I'm a little clueless. But the concept of the bass / treble you quickly understand (we are still not nag), but regarding the 'freq' and 'outline' I would say that it is the control, respectively, the high mids and low mids. Not obvious ...
In conclusion, the addition of these settings can be useful for followers, but may also lose fans (who will then turn to the Bluesbreaker II but lose the gain).

In short, it is not very clear, but there is no reason to seek and fiddling the buttons to adjust the sound. Go below!

SOUND QUALITY

! WARNING!
Due to that I bought my copy in a deposit-sales, and given the sound of the distortion mode, it is possible that mine is malfunctioning at this level. I therefore based solely on the OD mode, and believe me seen the number of buttons and headroom that has this pedal, there are already enough to make ;)

When you turn it on, do not turn the gain too high (2 or 3 should be enough to start slowly) and put all the buttons at noon, it might help to find his sound.
This is a very hard rock pedal and a very powerful and aggressive sound ... perhaps too much so. To try to describe the sound, it could be compared to that of Jack White or Raconteurs (Jack White), and it is not always easy!
I think that spending a lot of time on the settings to find a sound that suits you and do not let your best friend the metaleux to all buttons background to play hard and fast or you will lose a friend!
I have not found my happiness, but I do not despair, the freq and outline buttons are still beyond my understanding but I could find!
Tip: Do not rush!

OVERALL OPINION

I use it for more than a month, and having to give up the distortion, I lean heavily on one end, which allows me to fine-tune each setting: not easy!
I was looking for a wild drive pedal and I found it lacks me the leash (a compressor, to go after the metaphor? ^ ^)
As the pedal was only 40 € I did not want to try other pedals in 1000, and I jumped at the chance. At this price, it's not worth bothering the store. When I dépasserais 150-200 €, then I would!
What I love is the number of settings (I feel to repeat) and incredible headroom (already said I'm sure!) If that is not enough, it is you are looking for a distortion!
Ironically, what I like least is the number of settings: what crap! Unlike some pedals that need only to be connected to sound, you have to fight with that.
Excellent quality and price occasion as well as new, with the experience I do not have that choice out of curiosity. As I try to listen as much as possible sounds, I would take a pedal in the same price range to expand my knowledge!

pedal must

By goldorock, 05/07/2013
it simulates the lights but it does it very well!

UTILIZATION

everything is simple, but must be set above the last knob (top)

is the doc with 4 presets

SOUND QUALITY

Hi
I was looking for a pedal with a Marshall grain but sth strong and then I just
autan that jcm 800 2000 and I would even say almost fuzz or jmp (large grain drooling)

I couple with a bbe sonic stomp + qq boss blues driver times and frankly solos are super nice
hot and it has nothing to envy to a pedal lamp may be too "big" in the apartment
too powerful
there with a tube amp, it has what it takes but must adjust especially the last knob
on the other hand, so the overdrive is great but the cold or dark distortion if you want

I j fuzzy with js 1200 and I had a large grain to compensate for thin sounds and there is great!

OVERALL OPINION

No, but if not, should see the other brands that also simulate Marshall

ON really grain Marshall at home

ON can surely do better, but it is more expensive and must seek
there, for the price, this is a must have!
